Quantum physics vs. quantum mechanics

Click For Summary

Discussion Overview

The discussion centers on the distinctions between quantum physics, quantum mechanics, and quantum field theory. Participants explore whether these terms represent subfields within a broader category or if they are independent areas of study.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants suggest that quantum physics may be a broader subfield encompassing quantum mechanics and quantum field theory, while questioning if these are independent subfields.
  • Others argue that the categorization of these terms may not hold significant importance unless it affects the practice of physics, citing examples like the distinction between fermions and bosons.
  • A participant notes that terminology may reflect the intended audience of educational materials, with "quantum physics" being more accessible for beginners and "quantum mechanics" being aimed at graduate students and researchers.

Areas of Agreement / Disagreement

Participants express differing views on the significance of the distinctions between the terms, indicating that there is no consensus on their categorization or importance.

Contextual Notes

Some assumptions about the definitions and implications of the terms remain unresolved, and the discussion does not clarify the relationships between the subfields definitively.

I've been thinking about the difference between quantum physics and quantum mechanics. What are the difference?

Is quantum physics just a subfield name, and within that there are quantum mechanics and quantum field theory etc. or are all of these three independent subfields of physics?

Is there a reason why you put THIS much effort into what goes in a "name" such as this?

For me, this type of categorization has no significance and is quite interchangable. It is when a name effects the workings of physics and how it is practiced, then it matters (example: a "fermion" is not interchangable with a "boson" where the characteristics matters).

I apologize for the inconvenience.
 
in the common sense, if one's book use quantum physics
this book is written for beginners.
while quantum mechanics "terminology" is written for graduate oriented students and researchers.
